We're dividing 249643 by 86 
We want to divide 249643 by 86.

Let's proceed to step 1:
86 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 86

Moving on to step 2:
If we divide 24 by 86, we get 0 and a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 86

Let's proceed to step 3:
249 divided by 86 is 2 with a remainder of 77.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 172 from 249 leaves us with 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 86

Moving on to step 4:
86 goes into 776 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 774 from 776 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 86

Let's proceed to step 5:
86 goes into 24 0 times with a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 290.0
If we take 0 away from 24, we end up with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 86

Moving on to step 6:
86 goes into 243 2 times with a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 2902.0
Subtracting 172 from 243 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 7:
86 goes into 710 8 times with a remainder of 22.
The next digit of our result is 8. 
Result so far: 2902.8
If we subtract 688 from 710, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
86 goes into 220 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 2902.82
Deduct 172 from 220 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 9:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 2902.825
Deduct 430 from 480 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
The number 86 fits into 500 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 2902.8255
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 2902.8255 with a remaining 0.0007.
